gameplay modes of WMW

Working Memory Workout does much more than the N-back's basic "does this equal that" gameplay. I tried to explore as much as possible, and came up with 12 additional modes, using a maximum of 4 stimuli simultaneously.

inequality all
q: are all of these >, <, or = their previous? (all stimuli move in the same direction)
min stim: 2
max stim: 4

inequality most
q: are most of these >, <, or = their previous? (2/3 or 3/4, at minimum, move in the same direction)
min stim: 3
max stim: 4

one match
q: of these, exactly which one = its previous? (the others will not =)
min stim: 2
max stim: 4

one mismatch
q: of these, exactly which one is not = its previous? (the others =)
min stim: 3
max stim: 4

one (mis)match
q: of these, exactly which one stands out, being the only match or only mismatch?
min stim: 3
max stim: 4

types
Software is nifty for re-use. For each of the above modes, minus the inequality ones, we add a clone, but these clones don't change the value of the stimuli (1 vs 3; a vs e), but rather change the type of the stimuli (1 vs e; a vs 3).
